When Huckleberry catches up with Joe on his new raft, and jumps onto the pier, the water level is very low. Minutes later, when they head for the pier, the pier is almost submerged. Then, in the next shot, the water level is a bit lower.
At the end of the movie when Huck gets back to the raft after speaking to Jim for the last time, the raft is tied to the pier with rope. Huck didn't tie the raft to the pier when he jumped off the raft to go to Jim.
